“…of NiCr/NiSi TFTCs could be seen in our previous reports. [35][36][37] Besides, the uniformity of Ni and Cr in NiCr film, as well as Ni and Si in NiSi film, are also important, which could influence the characters of NiCr/NiSi TFTCs. So, EDS mapping is also carried out onto TFTCs, it has little influence onto the dynamic calibration results in Figures 1 and 2, especially for the violent oscillation in t 3 stage.…”

In order to reveal the dynamic response characteristic of thin film thermocouples (TFTCs), the nichrome/nisil (NiCr/NiSi) TFTCs are prepared onto the glass substrate. With short pulse infrared laser system, NiCr/NiSi TFTCs are dynamically calibrated. The thermoelectric electromotive force (TEF) curves of NiCr/NiSi TFTCs are recorded by the memory hicorder system, which could reflect TEF signals with resolution ratio in nanosecond and microvolt, simultaneously. With increasing laser energy from 15.49 to 29.59 mJ, TEF curves display more and more violent oscillation, even negative value. The results show that the bounce of thermal energy happens between two interfaces of TFTCs because the thermal conductivity of glass and air is significantly lower than that of NiSi/NiCr TFTCs. The bounce of thermal energy results in the obvious decrease of nNiCr and nNiSi, as well as oscillation of TEF. For laser energy in 29.59 mJ, the bounce of thermal energy in NiCr film could result in nNiCr < nNiSi. Then, TEF value appears abnormal negative value. Based on the results, the complex thermal energy transport process in TFTCs dynamic calibration is revealed, which results in the oscillation of thermal energy and TEF signal.

In recent years, fire and explosion accidents caused by high temperatures of lithium-ion batteries have become increasingly frequent, and the safety and reliability of batteries have been of great concern. Battery temperature monitoring is an important means to prevent the occurrence of safety accidents, but at present, it mainly focuses on the external temperature and lacks the monitoring of internal temperature changes and measurement of physical parameters of the battery, which makes it difficult to effectively solve the safety problem of the battery. In this paper, starting from the thermal runaway safety problem faced by Li-ion batteries, we analyze the heat generation principle and temperature effect during battery operation, and discuss various methods of internal battery temperature monitoring, including in-situ temperature measurement, multi-parameter measurement inside the battery, temperature measurement based on thin-film sensors and distributed fiber optic sensors, and impedance-based temperature estimation. Also, the advantages and disadvantages of different sensing techniques are compared, and the challenges of inserting temperature sensors into real batteries are reviewed. Finally, this paper presents directions and difficulties for future research on internal temperature monitoring of Li-ion batteries.
